LITTER-CARRIER.

To all 107mm, t may concern.'

Be it known that l, ALviN C. PnnKINs, citizen of the United States,residing at Goodland, in the county of Newton, State of Indiana, haveinvented certain new and useful Improvements in Litter-Carriers; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable othersskilled inthebart to which it appertains to make and use the same.

This invention relates to new vand useful improvements in elevatedcarriers, and particularly 'to carriers for conveying litter fromstables and barns.

One object'of the present invention is to provide a litter carrier whichincludes im` proved means for automatically releasing the carrier bucketso that it will easily dump its contents.

Another object is to provide a novel form of latch which engages withthe bail of the carrier bucket, and which is automatically released fromsuch yengagement when a trip engages with a projection on the overheadtrack, the latch being arranged to automatically rengage with the bailafterthe bucket has been dumped' and restored to its proper position.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawings. f

Referring' particularly to the accompanying `dra-wings, 10 represents anoverhead vtrack on which the carrier. is suspended,

said track being composed of two angle Specification 'of Letters Patent.

strips, as clearly seen in ings.

The carrier includes a frame composed of the horizontal meta] bar 11 tothe oppo site ends of which are secured the depending castings 12 and13, each having a bearing 14 in its end rotatably su )porting one end ofa winding shaft 15. hlounted on a stub shaft 16, carried by the casting12, lis a large grooved and toothed wheelV 17, and engaged in the grooveof this wheel, and with the teeth'thereof, is an lendless chain 1S whichis adapted to be drawn by the operator to rotate' the `whe-el.` On theend of the shaft-.15, yadjacent the wheel 17, is a worm wheel 19, whichmeshes with a worm 19 on the shaft 16, whereby when the wheel 17y isrotated the winding shaft 15 will be rotated. kA pair of chains 20 eachhas one Fig. 2 of the drawend secured to the shaft 15, and the other endsecured to the barvll.

An elongatedbucket 21 is disposed below the carrier frame, and pivotallyconnected to the opposite ends ofthe bucket are the arms 22 of the b ail,3. Secured to the lower sidefot the transverse portion of the bail. 23are the pulleys 24, and engaged with these pulleys are the intermediateVportions of the'chains 20. Thus, when the wheel 17 is rotated, and thismovement communicated tothe shaft 15, the chains 20 will be wound 4onsaid shaft, or unwound therefrom, with the result that the bucket willbe raised or lowered, in accordance with the direction of rotation ofthe wheel' 17. Secured to and extending above the castings 12 and 13,are the track engaging wheels 25, the same being mounted in pairs to'rnnAon the horizontal flanges of the angle strips of said track, and onopposite sidesv of the vertical flanges thereof. y

On each end of the bucket aremounted the loop brackets 31 in which arerotatably Asupported the shafts 30 and 30', formed with side recesses 32in which are received the adjacent ortions of the legs of the bail23, tomalntain the bucket in upright position.

I The forward end of the shaft 30 is formed with a downturned crank arm29, while the corresponding end of the shaft 80 is formed, with anupturned crank arm 29. Disposed longitudinally of the frontof the bucketis a rod.27`l1`aving its end portions pivotally connected'with the'crankarms 29 and 29 VOne end of the rod 27 is turned upwardly,

` as shown at 28. A coil spring is secured Vat its ends to the bucketand rod 27 to yieldably'hold the rod at one end of its move ment andmaintain the latch shafts 30 and 30 in operative position for engagementwith the arms of the bail.

Pivotally mounted on -the intermediatev portion of one side or" the bar11 is a vertically disposed bent lever 34 to one end of which is pivotally connected the` lower end of a vertical trip bar 35. This tripba 35 is mounted in guide brackets'carried'by the'bar 11, and has atransverse Vportionv 35 l.

on its upper end for engagement with the block 3.6 secured to the lowerfaces of the lhorizontal portions of the track, saidl block beingbeveled in opposite directions, longi-l tudinally of the track, and onits lower face,

for the purpose oit depressing said Ytrip bar o when the portion 35engages therewith. A

' bracket37is mounted on the outer end face of the casting 13, andpivotally supported in this bracket is a vertical lever 38,v the upperend of said lever beingpivotally connected with the'otherend of the bentlever ,31%, by means of the link 39. which extendsV longitudinally overthe bar 11 of the bucket cairier'frame. The lower end of the lever 38 isdisposed inwardly of the upper-end of the arm 28 of the slidable rod 27,in such position that when'the lever 38 is rocked on its pivot the samelower end will engage Withthe arm 28 and move the rod 27longitudinallyof the bucket. The other end of the rod 27, being connected to the crank29,r

'will causeythe latch member to be rocked in its brackets and out ofengagement with the arm of the bail 23. The bucket .is thus released andmay be easily and quickly tilted andits contents dumped. This releasingof theflatch'member is automatic in its operation and is accomplished bythe engagement of the trip bar 35 with the block 36 on the track.Y lhenthe portion 35 of the trip bar 35 engages with the beveled face of theblock, said trip .barwill be Vdepressed with the result that the bentlever 34 will vbe rocked on its pivot, pulling on the link 39 androcking the lever 38 into engagement with the arm 28 and .sliding therod 27 in the guide loops 26, and vrocking the latch member 30 out ofengaged on theshat 1.5 in opposite directions soy ythat when the shaftis rotated in one directionthey will unwind from the shaft andV lowerthe vbucket so that thesame can be loaded. Vhen the bucket is loaded thechain 18 is manipulated to Ywind the chains 2O on the shaft 15 and raisethe bucket. The carrier is then moved along the track to the point ofdumping, when'the trip lever v or bai' 35 will engage the block 36 andre? lease the notched portions 32 of the shafts 30 and 30 from the armsof the bail. The bucket is then tilted to dump its co-ntents, andthechain 18 again manipulated to raise the bucket, after the same has. beenswung up by hand, -into level position and the latches rengaged with thearms of the bail.
